JOHN L. HIVELY, OF ELKHART, INDIANA.

RESPIRATOR OR INHALER.

SPECIFICATION forming part of Letters Patent No. 790,057, dated May 16,1905.

Application filed June 22, 1904. Serial No. 213,695.

To all whom it may concern: I

Be it known that I, J OHN L. HIvELY, a citiof Elkhart, county ofElkhart, State of Indiana, have invented certain new and usefulImprovements in Respirators or Inhalers, of which thefollowing is aspecification.

' This invention relates to improvements in respirators or inhalers.

The main object of this invention is to provide an improved respiratoror inhaler which is comfortable and convenient to use and simple instructure.

Further objects and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

Theinvention is clearly defined, and pointed out in the claims. 1

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawings, forming a part of thisspecification, in which Figure 1 is a front elevation View of myimproved respirator or inhaler. Fig. 2 is a horizontal sectional viewtaken on a line corre-' sponding to line 2 2 of Fig. 1. Fig. 3 is'avertical sectional view taken on a line corresponding to line 3 3 ofFig. 1, the doorC being indicated in its open position by dottedprovided with a cushion A, preferably of rubher, which insures a perfectlit, to exclude air and also protects the face of the wearer. The

at one end to serve as a door therefor.

mask A is preferably stamped up from sheet metal, aluminium beingpreferred on account of its lightness, although any suitable materialmay be used. A retaining band or strap E, adapted to pass around theback of the head of the wearer, is provided. This band is permanentlysecured at one end to the mask, and its free end is provided with asnapbutton-socket member a to engage the stud member (4 upon the mask,so that it is quickly secured or detached. A slide-buckle c is providedfor adjusting the band.

Secured within the mask in such position as to be supported beneath thenose of the wearer when adjusted for use is a transverselyarrangedreceptacle B, having perforations b b in the top and bottom thereof,respectively. This receptacle B is filled with absorbent or medicatedmaterial F.

The rear wall B of the receptacle is hinged perforations Z) in .the topof the receptacle are zigzagged in relation to the perforations 6 in thebottom.

The mask is provided with a door 0 below the receptacle B forconvenience in expectorating or in administering medicine 7 or the like.This door is hinged at the top. Air is admitted to the mask throughperforations 0 in the door C. These perforations open into thereceptacle C, carried by the door. This receptacle is also provided witha filling of ab- The sorbent or medicated material F. The receptacle Cis provided with perforations 0 in its top, adapted to be brought intoregister with the perforations b in the bottom of the receptacle B whenthe door is in its closed position, so that the air is first drawn intothe receptacle G through the perforations c and passes through the samethrough the receptacle B.

The reccptacle'C is-provided with a door G.

(See Fig. A finger-piece 0 is provided for the door O. The door C. isheld in its open and closed positions by a blade-spring D, which'issecured to the mask and projects downwardly. When the door is open, itis engaged and retained by the lug d on the spring D.

With the parts arranged as described they are very compact, and thestructure is very convenient and comfortable to use. The material F forpacking the receptacles may be any suitable absorbent or medicatedmaterial. I preferably provide an absorbent material for the receptacleC, adapted to collect impurities, and a medicated material for thereceptacle F, so that the air inhaled is freed from its impurities andsuitably medicated. The medicated material is thus kept comparativelyfree from impurities, so that it is not necessary to renew the same asfrequently as would otherwise be the case.

I have illustrated and described my improved respirator or inhaler maskin detail in the form preferred by me on account of its structuraleconomy and convenience in use. I am, however, aware that it is capableof considerable structural variation without departing from myinvention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1.
